Title:
  KDE powermanagement crashes kernel

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have a Dell Latitude D6510 running (K)ubuntu 13.10 with the current
  kernel (3.11.0-14). In KDE when I pull the power cord, the system
  instantly freezes - completely, leaving no helpful traces of the cause
  in syslog or pm-powersave.log.

  It does not happen w/o a running KDE session or when I switch to Unity
  or XFCE. Hence, I suspect KDE triggering the bug.

  Googling for "power unplug crash linux kernel" yields a bunch of
  somewhat similiar issues, but those all seem slightly diffrent from
  what I see. In fact, I have had the/an "unplug crash issue" before
  like a year or so ago. Somehow it vanished, and now it is back again,
  so this could be a kernel regression.
